  1. aToo damaged to identify beyond genus level
  2. Notes: For each mosquito species, total number of individuals captured throughout the study period, number of pools tested for the presence of Dirofilaria immitis DNA, number of positive pools, percent positive pools and maximum likelihood estimate (MLE) are reported. The land-use types from which the positive pools were collected are denoted in parentheses after the total number of positive pools by species. MLE values give a point estimate of the infection rate per 1000 individuals
